HATERS BE HATIN'!!!!!
Aaron Rodgers' younger bro, Jordan, made his debut as a suitor on "The Bachelorette" Monday night -- and while he was a HUUUUGE hit with rose-giver JoJo Fletcher ... the dudes were SUPER JELLY PANTS!!!
Besides winning the first impression rose -- which puts him through to next week -- JoJo was clearly into the 27-year-old ... and even made out with the guy in the middle of the show.
Jordan's fellow competitors clearly feel threatened -- and reacted by spewin' hate.
